To all 1li/tom?? may concern: p

Be it known that l, Enron FnLLno'rH.

a citizen of the United States, resident of Minneapolis, county ofHennepin, State of Minnesota, have invented certain new and usefulImprovements in Tire Gauge Cutters, of which the following is aspecification.

The object of my invention is to provide a machine by means of which adiscarded or worn tire shoe or casing can be cut transversely into aseries of independent sections to be afterwards joined together by aflexible means and used on a wheel tire to serve as a guard orprotectortherefon f A further object is to provide a machine adaptedparticularly for cutting tires transversely which have no reinforcingwires in their beads or lips.

Other objects of the invention will appear from the following detaileddescription.

The invention consists generallyinvarious constructionsandcombinations,all'as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming` part of this specilication, v

Figure 1 is a side view of a tire guard cutter embodying my invention,

Figure 2 is a sectional view on the line 2-2 of Figure 1,

1 Figure 3 is a view on the opposite vside of the machine from theviewvshown in Figure 1,

Figure 4 is a vertical sectional view,

Figure 5 is a detail sectional view show! ing the base and the supportto which the saddle supporting the tire to be cut is secured.

In the drawing, 2 represents a suitable base, and 3 upright standardsthereon. 4 is a guide plate arranged vertically between the standardsand secured thereto, preferably by screws 5. 6 is a block, the upper endof said block terminating below the corresponding end of the plate 4 andforining a shoulder T. plate 8 is secured to the base 2 and has aslightly curved outer` end 9 and a block or saddle 10, preferably ofwood, seated on the plate 8, has a tongueL 11 that rests upon theshoulder 7 and is butted against the plate 4 and also has Contact withthe vertical outer face of the block 6. A socket 12 is provided in theunderside of the block to receive an adjustable screw 13 which serves tohold the block in place.l slight tilting thereof being` accomplished bythe adjustment of thescrew. Y

The tire to be out is placed over the saddle 10 with the portion to besheared ofi' proliecting beyond the' plate 4, which serves as a guidefor the cutting knife. Blocks 14 and 14l are inserted between rthestandards 3 and the plate 4, and pins 15 projectfrom the blocks throughthe blocks 14 into .sockets 16 in the base for holding both the blocksin place.. For a `large size tire, the blocks 142L are removed and theblocks l14 setgdirectly on the base. allowing the tire to lit snuglyover the guide plate 4,'with the beads restingon the `curved surfaces17. Blocks of various thickness may be used and removed, as desired.- Ii 4 A lever 18 has link 19 pivotally connect# infr one lend thereof`with the base and a .40 is mounted von said lever by means of a i 21andhas a seat/for a knife blade 22 and is vertically slidable in guides23 in the4 inner .faces of the standards This knife has a concavecutting edge 24 conforming substantially tothe shape of the tire, `so`that when the lever is forced down. the knife blade will contact withthe walls of the tire with a shear cut andsever the same transverselyinto a Series of independent sections. These sections are allsubstantially of the same size and to provide a uniform width of cut, Iarrange stops on the discharge side of the machine consisting of bars 25pivoted at 26 on the standards and adapted to swing into the?` path ofthe beads on the tire and arrest the feeding movement of thel tire aftereach severing operation. s, i l

This machine is designed'for cutting'tires or shoes in which there is nometal reinforcing means, the severing blade cutting smoothly and easilythrough the fabric of the .tire and separating `it into a plurality ofnarrow faced sections which `areadapted to tit the surface of a tire inuse and when joined together at the ends, form a substanvtial guard forthe tire.

erk

For dierent sizes of tires the blocks and s the part 10 may bechanged'or adjusted to ysuit different conditions of use and in variousways the details of construction herein ions shown and described may bemodified and i claim as my invention:

'i. Si n l fr the class describ .d comprising a bese. a f i mountedthereon and hafino; a rin"- sadisfar- Ance of a tire shoe to Liallv tothe inner provide a substr Aial support therefor. said adiaceut the basenav up n which 'andend ci said seat Airds the end oi the tire to besevered is inserted, resting' upon said seat-r and a seven knife mountedto out the tire transseiy into a se ies guard seci'fiouf-1.

2. ve o the class described com prising a buse having' a seat thereontor the main bodv or' the tire to be severed and curved surfaces toreceive and support the beads ot the tire, and a vertical@7 moving knifemounted to and sever the tire transverser)7 adjacent to said supports.

ne or the class described comprisine` a r e having seaty adapted toenter and support a ytire to be severed transversely, blocks mounted onsaid base and hay 'u surfaces adapted to engage and supiiiort the tirebeads, stops 'for liinitinf: the tecding movement or the tire on itssupport. and a severingkniiie having vertical gui s upon opposite sidesofsa-id sent for cut-tino' the tire transversely into series ot guardsections.

il. A machine o, described comn prising a base l upright plate thereon,standards upon opgosALU sides ot said plate, a block secured to saidplate and having` a shoulder at its upper end, a tire seat mounted onsaid base and having` a tongue to rest upon the shoulder of saidlprising` a en c;

block and bear against said plate, said seat having a socket in itsunderside and a screw adjustabiv mounted in said base and looselyvi,.liiu said socket, and a knife ind to uiove vertically near said plateVi said standards to sever the'projectend a tire restingon said seat;

macl ine oi" the class described coinnrisinqj a base9 a tire. seatthereon, a` severing e having); a cru-ved cutting' edge for engaging andsevering); the tire transversely, blocks removably mounted, one abovethe ot ier, on each side ot said seal;` the upper blocks having curvedseats to receive the ieads oia the tire and the lower blocks being;rei'novable to adapt the device For tires of dii'i'erent sizes.

6. ,x machine ot the Cluse described com- ,o having` upriffht standardsand a tire seat formed between said standards and spaced therefrom andhaving` an upper surface adapted to receive the tire be severed. blocksarranged in the space between said seat and J i standards and havingsurfaces to 'lit the iria-.ce oic the tire beads, and a sever ng; knifemounted to move verticallj in said standards and cutsaid tire intotransverse sections. c

7. A machine of the class described comprisinb base having as'eatthereon for' the tire tread, support the tire beads in combination Witha verticallT movable severing knife.

ln Witness whereof, I have hereunto set my hand this 28 day of Februaryi922.
